'7 Claims.

My invention has :for V'its object `a cigarette lighter yoperating with liquid fuel of lthe :type including a slidingcover :adapted to concealA during normal `operation :the flint or theflike piece of pyrophoric material. AAccording tomy invention, the spring urging said vflint or pyrophoric -part against the frictioniwheel, locked :in position by an 'auxiliary'stop normally engaging the rear `of the movable cover inside which the spring is fitted. This Lallows the inspection or .renewal :of the iiint to be operated bysshifting ythe rstop aside against the 'actionof a further spring arranged preferably in va tube, alongside of the longitudinal lighter wall. Thus rthe lrst mentioned spring is allowed :to expand and .to drive backtheimovable cover so as :to release the 'flint or the like part that may be removed if desired.

My invention `has for its object in 4association with the arrangement vvdisclosed a spring voperatedsystem for urgingthe c'over or lid into eitherfits closed `oropen position through .a connecting link controlled by a spring larranged 'horizontally 'inside a guideway lthe axis of which passes through the hinge ofthe cover whereby said cover-may be operated in particular for 'the removal 'of the flint without any transversal :movement of the spring being required, Isaid spring assuming merely an axial deformation.

The different 4control 'means referred to are carried by a common "plate that imay be screwed on to the body of the lighter.

The invention will be readily understood fby referring to the accompanying drawing illustrating an embodiment ofthe invention in which:

Figure 1 shows a vertical :section on the line 1--1 of Fig-ure 5;

Figure 2 shows the same section after 'removal of the cover;

Figure 3 shows a vertical section on ythe line 3--3 of Figure 5;

Figure 4 shows the same with the c'ovler of the cigarette lighter closed;

Figure v5 shows a plan view.

According to the invention, in the position shown by Figure l1, the cover 2 sliding in .the part 3 'fixed to the body of the cigarette lighter i4 by the screws 15 keeps the :spring G'compressed `v'vhich spring presses the `pyrophoric 'material 'TI against the roller 8. An abutment :9 forced out of its recess I0 by a spring I I holds, the cover '2 in this position. In order to change o r replace the material 1 it is' suiiicient to 'depress the lateral projection I2 of the abutment 9 as shown in. Fig. 5 soy as to constrain such abutment to recede into its recess. The .cover 2, released under ythe action 2 of the spring 6, iis thrust against the open lid 13 ofthe cigarette lighter 4 .(Figure22). Thefpyrophoric material 'I is easily accessible for the 1purpose of replacement or inspection I-through the aperture I4. In order to close 'the aperture t4., it is sufficient to move the cover in .the direction of the roller until lthe abutment 9 again locks it.

Another feature ofthe cigarette lighter according to the invention is the means-serving 'to keep ythe hingedlid I3, hinged at i9, in either extreme lposition which it can occupy.

For this purpose a crank lever 26 is 4hinged at 2| to afconnecting member -22 the head 2-3-fof which is 'supported in a cup forming a knuckle joint provided at the extremity of a member 24 which slides longitudinally in :a cylindrical recess 25 and compresses the spring 26 housed in .said

recess.

Figures Band 4 show the two extremeopenand closed positions in which the lid I3 isheld under the control lof thespring'26 `through the intervention of .the member 24, of the connecting member 422 and the crank lever 26.

In order to shift the said lid from vone position tothe other, it is moved by hand'until the hinge .2| of the connecting member and of the crank lever 20 has passed over the line joining the centre of the cup of the member 24 to `*ax-is ofthe hinge I9; the thrustof the spring L26 `then `completes the movement.

In the opening movement of the lid I3, the crank lever 20 is stopped by the abutment 21,the purpose of which is to relieve the saidihinge which thus does not quite reach the end of its stroke;

As shown in the accompanying drawing, all the members, viz: cover 2, springs 6 and 26, are carried by the same part of lplate 3 xed to vthe body of .the cigarette lighter 4 by the screws 5 which permit simple dismantling, thus facilitating cleaning and replacement of parts.
